Axis hole 21 in outer ring 22 and hub 1 is rotatably assorted.The beneficial effect so obtained is the freedom degree for the shaft that rotating vane 6 rotates
It is restricted, the slow-roll stabilization of rotating vane 6.
In some embodiments, the example of the structure of the extension of protruding shaft 62 includes but is not limited to as shown in Figure 1 to Figure 3
Protruding shaft 62 extends protrusion along the longitudinal edge of rotating vane 6, although there is also other extended structures.In at least one embodiment,
Protruding shaft 62 along rotating vane 6 longitudinal edge extend protrusion, so obtain beneficial effect be that 62 structure of protruding shaft is simple, it is easy to process and with
Axis hole 21 in outer ring 22 and hub 1 matches.
In one or more embodiments, the example for accommodating the specific structure of fixed bracket 2 includes but is not limited to such as Fig. 1
Fixed bracket 2 is accommodated using cylinder shell 8 to shown in Fig. 3, although there can also be other shapes to accommodate fixed bracket 2.?
In at least one embodiment, the shell 8 of wind outlet unit 101 is cylinder shell 8, cylinder shell 8 provide it is circular go out
Air port, fixed bracket 2 are arranged in cylinder shell 8.The beneficial effect so obtained is can produce using cylinder shell 8
The air-flow of rotation accelerates the flow velocity of air-flow in air purifier, to improve the treatment effeciency of air purifier.
In some embodiments, the example of the direction of air outlet includes but is not limited to the axis of air outlet as shown in Figure 5
Line L2It is inclined relative to horizontal, although there is also other directions for air outlet.In at least one embodiment, the axis of air outlet
Line L2It is inclined relative to horizontal, the beneficial effect so obtained is to expand air-out area, improves air purification efficiency.
The wind outlet unit 101 of the air purifier of above-described embodiment is, it can be achieved that such as Fig. 4 to working condition shown in Fig. 8
With the switching of closed state.As shown in figure 4, rotating vane 6 completely closes air outlet when air purifier closed state, avoid closing
Dust when closed state in air, which is fallen into, causes secondary pollution inside air purifier.As shown in figure 5, when air purifier starts
When work enters working condition, the rotation of motor 9 drives driving gear 7 to rotate together, and because of driving gear 7 and conicle
Gear 5 is meshed together, rotates together so will drive small conical gear 5.When driving gear 7 turns an angle, turn
Leaf 6 also turns an angle as shown in Figure 6, so that air outlet partially opens, the working condition for defining air purifier at this time is
General state.Under general state, from fig. 6, it can be seen that the air-out direction of air purifier includes lateral and vertical outlet air,
The air-out area of such clarifier increases.Similarly, as shown in Figure 7, Figure 8, driving gear 7 further rotates, and rotating vane 6 turns to pole
Extreme position, i.e., vertical with fixed bracket 2, air outlet fully opens, and the working condition for defining air purifier at this time is standard-sized sheet shape
State, the vertical air-out area of air purifier is maximum at this time, and outlet air is not easily susceptible to the blocking of surrounding furniture.When air purifier needs
When closing, motor is rotated toward opposite direction, and rotating vane 6 is driven to close air outlet.
To sum up, the wind outlet unit 101 of above-described embodiment is by realizing the switching of working condition and closed state, air
In working condition, the air outlet angle of wind outlet unit 101 can adjust clarifier as needed, overcome the sky of merely transversely outlet air
Gas purifier stops with air purifier height limitation itself and the low deficiency of purification efficiency vulnerable to furniture；Similarly, air
Clarifier in off position when, the rotating vane 6 of wind outlet unit 101, which turns to, completely closes air outlet, when avoiding in off position
Dust in air, which is fallen into, causes secondary pollution inside air purifier.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art without departing from the spirit and scope of the utility model, can make possible variation and modification.Cause
This, all contents without departing from technical solutions of the utility model, according to the technical essence of the utility model to above embodiments institute
Any modification, equivalent variations and the modification made, each fall within the protection scope that the utility model claims are defined.
